Wedway all-electric reefer power system generates zero emissions


Caspers Company and Emerald Technology Partners have partnered to release an all-electric kinetic-energy-powered semitrailer refrigeration system for transportation. The companies announced that the Wedway refrigeration power system, developed by Emerald, was placed into service in January 2013 and has been successfully tested with Caspers in the Tampa Bay FL area.

Based on patent-pending technology, when the trailer is in motion, the system powers the refrigeration unit through Wedway’s mechanical interface mounted on the trailer axle. By capturing kinetic energy generated by the trailer wheel’s rotation, the Wedway provides in excess the energy to run the system continuously and charge on-board batteries. When the trailer is stationary, the unit is powered by the lithium ion batteries for eight to 10 hours on standard power cell, or can be plugged into shore power through a commercial 240-volt outlet running indefinitely while charging the batteries.

The Wedway system uses no independent diesel, meaning there is no fossil fuel, oil, or filters to maintain—and zero emissions are generated.
